Description

Levier d'un dispositif de commande de variation d'inclinaison des projecteurs de véhicules automobiles, notamment pour la commande simultanée du basculement de deux projecteurs indépendants disposés à proximité l'un de l'autre, tels qu'on projecteur dit »CODE« et un projecgteur dit »ROUTE«.Lever of a device for controlling the inclination of the inclination of motor vehicle headlamps, in particular for the simultaneous control of the tilting of two independent headlamps arranged close to one another, such as a so-called "CODE" headlamp and a "ROAD" projector.

Pour réaliser un tel basculement il est connu dans le brevet FR-A-2 233 822, d'utiliser un levier de renvoi commun en forme de fourche dont les extrémités des branches coopérent chacune avec l'un des projecteurs considérés.To achieve such a tilting, it is known in patent FR-A-2 233 822 to use a common return lever in the form of a fork, the ends of the branches of which each cooperate with one of the headlights considered.

Il peut être très avantageux de réaliser cette commande de basculement au niveau de certaines vis de réglage initial d'orientation dedits projecteurs, ceci afin de limiter le nombre de points de fixation et d'articulation par projecteur.It can be very advantageous to carry out this tilting command at the level of certain initial adjustment screws for orienting the headlights, in order to limit the number of fixing and articulation points per headlight.

Or dans le brevet mentionné ci-dessus le levier de renvoi de commande est seulement offecté au basculement simulatné des projecteurs en agissant sur des butées d'appui solidaires desdits projecteurs, de plus il ne comporte aucune souplesse susceptible d'emmagasiner les règla- ges initiaux indépendants, les tolérances de fabrication, d'assemblage et de réglage, ce qui peut êtrenéfaste pour le bon fonctionnement d'un dispositif de commande équipé d'un tel levier.However, in the patent mentioned above, the control return lever is only authorized for simulated tilting of the projectors by acting on support stops integral with said projectors, moreover it does not include any flexibility capable of storing the initial adjustments. independent, manufacturing, assembly and adjustment tolerances, which can be detrimental for the proper functioning of a control device equipped with such a lever.

La présente invention a pour but de remédier à ces inconvénients et concerne à cet effet un levier d'un dispositif de commande de variation d'inclinaison des projecteurs de véhicules automobiles, notamment pour la commande simultanée du basculement de deux projecteurs indépendants disposés proches l'un de l'autre sur un support fixé par des vis de réglage qui se déplacent dans des écrous, au moyen dudit levier de commande unique relié à tourillonnement au support fixé, caractérisé en ce que le levier comporte au moins un bras de commande relié aux vis de réglage par un dispositif à cardan.The object of the present invention is to remedy these drawbacks and to this end relates to a lever of a device for controlling the inclination variation of the headlights of motor vehicles, in particular for the simultaneous control of the tilting of two independent headlights arranged close to the one on the other on a support fixed by adjusting screws which move in nuts, by means of said single control lever connected in a journalled fashion to the fixed support, characterized in that the lever comprises at least one control arm connected to the adjustment screw by a cardan device.

Les projecteurs 1 et 2, respectivement un projecteur pour le faisceau »route« et l'autre pour le faisceau »code«, sont assemblés indépendants et à proximité l'un de l'autre sur une même platine support 4 au moyen de vis 7 qui comportent des rotules 21 sur lesquelles lesdits projecteurs sont encliquetés. Sur cette platine est articulé un levier de commande (3) qui agit simultanément sur les deux projecteurs.The headlamps 1 and 2, respectively a headlamp for the "road" beam and the other for the "code" beam, are assembled independent and close to each other on the same support plate 4 by means of screws 7 which include ball joints 21 on which said projectors are snapped. On this plate is articulated a control lever (3) which acts simultaneously on the two projectors.

Conformément à l'invention et suivant un mode de réalisation le levier de commande 3, des figures 2 à 4 comporte un étrier 5 et un palonnier 6 qui relient les bras de commande 8 aux vis de réglage 7 par un dispositif à cardan.According to the invention and according to one embodiment the control lever 3, Figures 2 to 4 comprises a stirrup 5 and a lifter 6 which connect the control arms 8 to the adjusting screws 7 by a gimbal device.

Le bras de commande 8 est solidaire de l'étrier 5 et les vis de réglage 7 sont maintenues dans des écrous 17 solidaires du palonnier 6.The control arm 8 is secured to the stirrup 5 and the adjustment screws 7 are held in nuts 17 secured to the lifter 6.

Le palonnier 6 est constitué d'une armature 16 qui comporte d'une part des extrémités en forme de U ouverts vers l'extérieur dans lesquelles sont maintenus les écrous 17 par des liaisons verticales 18 et d'autre part en sa partie centrale, perpendiculairement aux bases de U et entre celles-ci, une joue 20 reliée aux dites bases par des tourillons 19.The lifting beam 6 consists of a frame 16 which comprises on the one hand U-shaped ends open towards the outside in which the nuts 17 are held by vertical connections 18 and on the other hand in its central part, perpendicularly at the bases of U and between them, a cheek 20 connected to said bases by pins 19.

Les liaisons 18 sont de section réduite et de préférence cylindrique de façon à pouvoir se déformer élastiquement sous l'action de forces représentées par les flèches A sur la figure 1.The connections 18 are of reduced section and preferably cylindrical so as to be able to deform elastically under the action of forces represented by the arrows A in FIG. 1.

L'étrier 5 est constitué d'une semelle 9 qui comporte sur un de ses côtés le bras de commande 8, qui est plus particulièrement un bras de commande manuel.The stirrup 5 consists of a sole 9 which has on one of its sides the control arm 8, which is more particularly a manual control arm.

Sous la face inférieure de la semelle 9 sont réalisés deux crochets 10 en forme d'anneaux cylindriques fendus aptes à encliqueter sur des tourillons solidaires de la platine support 4.Under the underside of the sole 9 are made two hooks 10 in the form of split cylindrical rings capable of snapping onto pins attached to the support plate 4.

Sur sa face supérieure la semelle 9 comporte trois joues parallèles perpendiculaires à l'axe de rotation des crochets 10, dont les deux extrêmes 11 comportentun berceau 13 des tourillons 19 du palonnier 6, et dont la troisième intermédiaire 12 est évidée en sa partie centrale et comporte à son extrémité libre une chape déformable élastiquement 14.On its upper face, the sole 9 has three parallel cheeks perpendicular to the axis of rotation of the hooks 10, the two ends of which 11 have a cradle 13 of the pins 19 of the lifter 6, and the third intermediate 12 of which is hollowed out in its central part and comprises at its free end an elastically deformable yoke 14.

Les berceaux 13 sont des trous cylindiques fendus longidudinalement dans lesquelles s'encliquetent les tourillons 19.The cradles 13 are cylindrical holes split lengthwise into which the pins 19 snap into place.

La chape déformable élastiquement 14 se compose de deux demianneaux 15 suspendus face à face et écartés d'un espace au plus égal à l'épaisseur de la joue 20 du palonnier 6.The elastically deformable yoke 14 consists of two half-rings 15 suspended face to face and spaced apart by a space at most equal to the thickness of the cheek 20 of the lifter 6.

Suivant une variante comme représentée à la figure 5 l'étrier 5 peut aussi comporter un bras 22 susceptible de recevoir l'extrémité d'un transducteur 23 d'une commande à distance.According to a variant as shown in Figure 5 the bracket 5 may also include an arm 22 capable of receiving the end of a transducer 23 of a remote control.

L'obtention du levier 3 s'effectue alors simplement par l'encliquetage des tourillons 19 du palonnier 6 dans les berceaux 13 de l'étrier 5, la joue 20 étant intercallée entre les deux demianneaux 15 de la chape 14.The lever 3 is then obtained simply by snap-fastening the pins 19 of the lifter 6 in the cradles 13 of the stirrup 5, the cheek 20 being interposed between the two half-rings 15 of the yoke 14.

Pour le bon fonctionnement d'un tel levier il est nécessaire que l'accouplement entre le palonnier et l'étrier soit rigide pour que toute action d'un des bras 8 ou 22 soit répercutée sur les écrous 17 et conséquemment sur les vis 7, mais il est indispensable, aussi que l'accouplement comporte une certaine souplesse susceptible d'absorber différents efforts notamment lors du montage des projecteurs 1 et 2 pour l'alignement de l'axe des vis 7 avec le siège de leur rotule 21 solidaire des projecteurs, ces efforts sont représentés par les flèches A, B, et C des figures 1 et 2.For the proper functioning of such a lever it is necessary that the coupling between the lifter and the stirrup is rigid so that any action of one of the arms 8 or 22 is reflected on the nuts 17 and consequently on the screws 7, but he is essential, also that the coupling includes a certain flexibility capable of absorbing various forces in particular during the mounting of the projectors 1 and 2 for the alignment of the axis of the screws 7 with the seat of their ball joint 21 integral with the projectors, these efforts are represented by the arrows A, B, and C in Figures 1 and 2.

De part la présence des tourillons 18 les vis 7 peuvent légérement être orientées suivant les lèches A sans préjudice pour la liaison entre l'étrier 5 et le palonnier 6.Due to the presence of the journals 18, the screws 7 can be slightly oriented along the lips A without prejudice to the connection between the stirrup 5 and the lifter 6.

Les vis 7 peuvent aussi être inclinées suivant les flèches B grâce aux tourillons 19 dans leur berceaux 13.The screws 7 can also be inclined according to the arrows B by means of the pins 19 in their cradles 13.

Il peut aussi apparaitre des efforts suivant les flèches C, les projecteurs n'étant pas assemblés simultanément, et dans ce cas l'étrier 5 et le palonnier 6 ne se trouvent pas dans un plan adéquat, la chape déformable élastiquement 14 assure alors un rappel automatique du palonnier 6 afin qu'il soit automatiquement replacé dans sa bonne orientation.It can also appear forces following the arrows C, the headlights not being assembled simultaneously, and in this case the stirrup 5 and the cross-beam 6 are not in an adequate plane, the elastically deformable yoke 14 then provides a reminder automatic lifting beam 6 so that it is automatically replaced in its correct orientation.

Suivant un autre mode de réalisation tel que représenté aux figures 5 et 6 le levier 24 est obtenu d'un seul tenant à partir d'une semelle 31 qui comporte comme celle de l'etrier 5 de la réalisation précédence des crochets 10, un bras 8 et peut comporter un bras 22; la semelle 31 supporte une armature 25 qui comporte de part et d'autre d'un axe de symétrie un anneau cylindrique 27 qui avec des tourillons 26 et 28 joue le rôle du cardan qui autorise les divers débattements angulaires des écrous 17. Chaque écrou 17 est relié concentriquement à l'anneau 27 correspondant par les tourillons 28 disposés verticalement, et chaque anneau 27 est relié à l'armature 25 par des tourillons 26 disposés horizontalement.According to another embodiment as shown in Figures 5 and 6 the lever 24 is obtained in one piece from a sole 31 which includes, like that of the stirrup 5 of the embodiment precedence of the hooks 10, an arm 8 and may include an arm 22; the sole 31 supports a frame 25 which comprises on either side of an axis of symmetry a cylindrical ring 27 which with pins 26 and 28 plays the role of the gimbal which allows the various angular deflections of the nuts 17. Each nut 17 is concentrically connected to the corresponding ring 27 by the pins 28 arranged vertically, and each ring 27 is connected to the frame 25 by pins 26 arranged horizontally.

Les espaces libres 29 et 30 sont donc inter- callès entre l'écrou 17 l'anneau 27 et l'armature 25 afin que d'une part l'écrou 17 puisse osciller dans l'anneau 27 grâce à l'espace 29, et que d'autre part l'anneau 27 puisse osciller dans l'armature 25 grâce à l'espace 30. Ainsi lors de l'inclinaison d'une vis 7 suivant la flèche A l'écrou correspondant 17 oscille dans l'anneau 27 grâce aux tourillons 28 déformables élastiquement, l'anneau 27 étant immobilisé par les tourillons 26 dans l'armature 25, et lors de l'inclinaison d'une vis 7 suivant la flèche B, l'écrou 17 et l'anneau 27 sont concentriques et fixes l'un par rapport à l'autre, l'ensemble défini par l'écrou 17 et l'anneau 27 peut donc pivoter dans l'espace 30 autour de l'axe des tourillons déformables élastiquement 26.The free spaces 29 and 30 are therefore interposed between the nut 17 the ring 27 and the frame 25 so that on the one hand the nut 17 can oscillate in the ring 27 thanks to the space 29, and that on the other hand the ring 27 can oscillate in the frame 25 thanks to the space 30. Thus during the inclination of a screw 7 along the arrow A the corresponding nut 17 oscillates in the ring 27 thanks to the elastically deformable pins 28, the ring 27 being immobilized by the pins 26 in the frame 25, and during the inclination of a screw 7 along arrow B, the nut 17 and the ring 27 are concentric and fixed relative to each other, the assembly defined by the nut 17 and the ring 27 can therefore pivot in the space 30 around the axis of the elastically deformable pins 26.

L'armature 25 peut se présenter soit suivant un ensemble fermé tel que représenté dans la partie gauche de la figure 5, soit ouvert et donc suspendu, tel que représenté dans la partie droite de ladite figure 5, par la partie centrale de l'armature réalisée entre les deux anneaux 27.The frame 25 can be either in a closed assembly as shown in the left part of Figure 5, or open and therefore suspended, as shown in the right part of said Figure 5, by the central part of the frame made between the two rings 27.
